Background: LC-MS/MS is recommended for accurately measuring circulating steroids. However, laboratories using LC-MS/MS adopt various pre-analytical and analytical strategies, and little is known about comparability of results. Whether different blood derivatives impact LC-MS/MS measurements is unclear, and the benefit of unifying the calibration system among laboratories was not tested.Aim: Comparisons of LC-MS/MS measurements of circulating aldosterone...
